Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This is a 10-year study of the Trident II acetabular component as part of total hip replacement at the Royal Infirmary of Edinburgh, NHS Lothian.
Patients will receive a Trident® II acetabular component as part of primary total hip arthroplasty at the study centre. This component is CE marked and widely available for use by UK surgeons. The Trident® II shells are HA coated, cementless, press-fit acetabular shells composed of a Titanium (Ti-6Al-4V) substrate featuring a CpTi roughened surface with PureFix™ HA. The cup is available in a range of sizes and is indicated for primary and revision procedures.
A standard operative technique will be employed by all study surgeons, using the posterior approach. The routine post-operative patient care protocol of the study centre will be employed.
10 year implant survival is the primary aim, but in addition functional and radiographical outcome will be assessed a 1, 2, 5, 7 and 10 years.
